Description

General description

Molecular sieve 0.3 nm is a porous solid that can be used in desiccators and drying tubes to dry gases and absolute solvents. It also changes its color from brown to yellowish at a water uptake of approximately 7-10 g/100 g molecular sieve.

Application

Molecular sieve 0.3 nm can be used as an adsorbent:

• To remove traces of moisture in chemicals.
• In ethanol-water mixture purification to obtain pure ethanol.

It can also be used as a catalyst in the condensation of hydroxylamine hydrochloride with aldehydes, ketones, and 1,3-diketones to synthesize aldoximes, ketoximes, and 1,3-dioximes respectively.
